I've come to the realization, and I'm completely embarassed to admit it, that proper sound treatment of my mixing room is as important, or even more important than all the fancy plug-ins I'm tempted to buy. I have a great set of Alesis studio monitors, flat response, but I couldn't figure out why my mixes always sounded like they were in a box when I took them outside and gave them the "car test", they never translated well to other sound systems. Was it the limit of what my DAW could achieve, or maybe the plug-ins added small sample delays giving a hollow sound, when I tried to EQ why could I not detect changes unless they were drastic?
The answer, is the environment in which I mix the music. So far, I've gone to my local music store and purchased three 2 x 4 panels and two "bass traps", all made of foam, black, and really they look kind of cool. Just these few additions have changed how I hear the mix by alot. But now, I want more! There's still a boomy bass resonance throughout the room, and these commercial panels are just way too expensive to treat the entire room.
I call this part one because I'm still in the middle of the process, but I thought I'd share what I'm doing because either it may help, or some of you acousticians can give some helpful advice. This is essentially a non-technical, trial and error process for me, I'm an ear player on bass, so I've got to go with playing this one by ear too.
I don't want to spout out all kinds of theories about bass traps, but here is one of the best resources I've found, that's not too technical for the average guy: http://www.ethanwiner.com/acoustics.html and there's lots of great info at http://www.realtraps.com
I work in construction in real life as an electrician, and I've talked to professional insulators on the job, and they had no idea what corning 703 or 705 was, and actually I'm not really sure myself. However, on further study, it appears that that the material is consistent with the density of what we call "mineral wool", which in construction is normally used for stuffing big holes for fireproofing. I went to my local commercial building supplier (not home depot or ace harware) and got five 2 x 4 x 4" thick sheets for 41 bucks. I also bought a box of cheap 2 x 2 ceiling tile. What I'm planning to do is to cut the 2 x 2 sheets in half, and the 2 x 4 batting in half longways, and dressing it up with some wood molding, covering all four walls at the top. In other words, there will be a 12" strip around the room at the top at a 45 degree angle, I will place the ceiling tiles cut in half at even intervals, with space inbetween, to hold the insulation, then dress the entire construction with some cloth. The important thing is to leave an air gap between your actual construction and what it rests on, ie the ceiling tile. I picked ceiling tile because I feel it will still reflect some higher frequencies, but will be a more sufficient barrier in combination with the mineral wool to not allow the bass back into the room, I believe it will allow the lower frequencies to pass one way, yet, remove sufficient energy for their return. Anyway, that's the hope :)

Very Cool! Thanks for the info. My next phase is taking a hard look at my room and treating it. This helped a bunch.

great set of Alesis monitors? Hmm.. what monitors are those? monitors are not Alesis' cup of tea...
but I digress...
no need to be embarrassed on the realization of how important acoustics of the mixing environment is, in fact you should be proud that your knowledge of sound production is now up a notch.
implementation of bass traps is a fantastic first step, that will minimize of bass buildups, especially if you place them properly. next should be a few diffusors to further reduce comb filtering.
what size is your mixing room by the way?
still, congratulations on getting started on better acoustics in the mixing room.

Great Tommy! Bill, Thanks for the great tips. Hi Gerry, that would be the Alesis M1 Active mk2 Biamp Monitors, they work well for my price range. The mixing room is 11 x 11 x 8 tall, totally bad dimensions for acoustics, but there is no other choice.

newton good post...most of us can't afford the auralex, etc. treatments...i made my own treatments out of celiing tile similar to what you mentioned....the one thing to note is the type of tile that is available...some are almost sheet rock while others are like a piece of insul...you can mix and mingle depending on your needs...i built several panels and covered with burlap...
bill are you saying that my current speaker placement might not be optimal (ie, in the closet)?? :) scary thing is i am learning how to mix better all the time in said closet...who needs a big room!?

hey i'll have to fool w/the tissue trick a bit...i actually put up some of my acoustic treatment boards up in my closet and realized my monitors had some adjustments for placement on the wall...all helped a bit as long as i keep the monitors at a soft level...
